Cocoa Programming

I just received my copy of Cocoa Programming. At first glance, the book seems a good update for Mac OS X development.

It has been quite a few months since I did Mac (and iPhone) programming. I have not looked deeply at Core Data and Grand Central Dispatch yet. I also want to experiment with Objective-C blocks.

I need to find a suitable idea for a Mac application to prototype and experiment. Any idea or suggestion is welcome!
